▼ In the transition to renewable energy, harvesting the power from oceanic waves is often mentioned to be next step after the deployment of wind energy technology. Although many different solutions for wave energy conversion (WEC) are being developed and financial support schemes exist, commercially extracting this energy seems however to be rather challenging. Major troubles are over-priced first projects and incapability to endure year-round oceanic conditions. While the costs are expected to reduce once a successful WEC-device enters large scale production, it is unclear what device type would be the most viable. This study presents a combination of available methods and tools that together allow to assess viability of WEC-devices in early stage of development. Prior to including economic factors, the most important aspect that defines viability is power performance. Comparing simulated power performance of different concepts for WEC is complicated by their different level of optimization of control strategies. Renowned studies that compared the power performance of various device types have been extended by calculating the viability for one particular promising device type: the quasi-rigid, submerged pressure differential device. This device appears promising being protected by its submerged position, while performing as if it was placed in the high intensity waves at the surface. The diffraction software tools commonly used for hydrodynamic calculations, could not be applied to calculate quasi-rigid (volume-changing) objects. For this problem a method is suggested which adds the functionality of panel selection to exclude surface areas of a body design for hydrodynamic calculation. In this thesis both the average power performance in time-domain simulations and the maximum power limits were calculated in order to compare the submerged pressure differential device to other point absorbing WEC-devices. The suggested methods contribute to defining a generic way of comparing future concepts for WEC to converge towards a single approach and select WEC-devices for investment.

▼ Stability and security of the grid are two vital aspects of energy supply. To keep the grid stable, it is necessary that the electricity plant can control and protect the mechanism. In the past, traditional plants could meet these requirements. Nowadays, the share of sustainable power sources in total electricity generation has become so important that these sources must keep the grid stable. A significant part of these requirements is the Low Voltage Ride Through (LVRT) capability of the sustainable energy plant. When some large loads are connected to the grid or as a result of grid faults like lightning strikes or short circuits, short–term voltage dip may occur. This low voltage dip condition plans to be simulated and the behaviours of Brushless Doubly-Fed Induction Generator (B-DFIG) should be improved in this situation. This thesis is going to realize this goal that after the improvement, when low voltage dip occurs, it is not necessary to disconnect the generator from the grid. The thesis is organized as follows: Firstly, the B-DFIG modelling is implemented, including the steady state modelling by equivalent circuits and the dynamic modelling by differential equations. The steady and transient state characteristic of B-DFIG can be studied by equivalent circuits and dynamic models respectively. Secondly, the control algorithm is added to the power electronic converter to control the machine in a stable and responsive manner. Thirdly, simulations of both full voltage and low voltage dip conditions are done to compare B-DFIG behaviours between these two different simulation conditions. Unexpected performance like large transient current will occur under low voltage dip condition. Fourthly, the LVRT control algorithm is added to the controller of B-DFIG for improving the behaviours of B-DFIG in low voltage dip condition based on some constraints and assumptions. Finally, experiments are executed to verify this result.

▼ Subsea pipelines are critical for oil and gas production and transport, more than 100.000kmof subsea pipelines have been laid. These pipelines are laid by specially designed ships which can lay these pipelines at great depth and a high speed. However, designing the supply chain to deliver joints (pipe pieces) to these pipe lay vessels can be very complex; there aremany possible supply vessel combinations andweather influences that can impact the supply chain. This makes trying to find a good solution a very difficult and time-consuming process currently with a lot of manual iterations. This is called the Allseas problem. To solve this supply chain problema mathematical model is developed, thismodel can solve the supply chain problem while taking into account the many constraints. The research question that is discussed in this thesis is: Can the optimal usage of supply vessels, required to solve the pipelay vessel supply problem, be determined using a scenario based mathematical optimisation model? This model can eliminate the need for the many manual iterations and deliver an optimal solution that the Logistics and chartering department can use. To supply joints to the pipelay vessels several different types of supply vessels can be used. These supply vessels have different characteristics such as; hold capacity, sailing speed, capital- and operational expenditure, and workability (ability to work in bad weather). The supply vessels must supply joints to the pipelay vessel which can have one or two pipe transfer cranes. The number of pipe transfer cranes that can be used significantly influences the speed at which the supply vessels can be unloaded. A final important influence on the supply chain problemis the weather; specifically the wave height and wind speed: they determine if a supply vessel can unload it joints, or if the pipelay vessel can lay pipe. The goal of the problem is to design a fleet of supply vessels that can deliver the cheapest possible set of routes that will supply all the required joints to the pipelay vessel on time. A scenario based mathematical optimisation model is developed to find the solution to the Allseas problem. Some important parameters for this model that are thoroughly researched are: the desired stock level of the pipelay vessel, i.e. how full should the holds be? The demand window, i.e. how close to the demanded number of joints should the model deliver. The final parameter of interest is the node duration, all joints must be delivered during a certain time window the parameter node duration changes the size of the time window. The influence of these parameters is also investigated when weather is simulated. The results of the developed program show that it is possible to make a mathematical model that determines the optimal pipe supply vessel usage. Some other interesting parameters settings have also been found by the model. Allseas always tries to keep the pipelay vessels stocked as full as possible, however, the mathematical model has shown that it ismore… Advisors/Committee Members: Schulte, Frederik (mentor), Polinder, Henk (mentor), Miedema, Sape (graduation committee), Delft University of Technology (degree granting institution).

When your dream yacht is being built at Feadship, the process starts with a blank page. This early stage is defined as the Sales phase. In consultation with a designer, the look and the feel of a yacht is easily captured. The expertise of the designer will lead to a yacht fitting the vision of the client. In the current process, the lines drawn on paper restrict the design freedom of the naval architect. Next, not all consequences of decisions are known, which leads to the probability of alterations in later phases. The current design method is called a point-based method. A single starting point is chosen, which is gradually refined in a couple of iterations. This method has some disadvantages. Design exploration is a method in which many solutions are generated in a design space and no single starting point is chosen. The main focus of this approach is to postpone the design decisions until they can be made with the required knowledge. This will prevent alterations and rework in future phases. In this research, there is investigated whether design exploration could be implemented in the Sales phase at Feadship, using design drivers for the exploration method. The design driver origin from the stakeholders (client, regulatory bodies and Feadship) and are used to structure the design requirements and to evaluate the solutions. Creating the design space is done with help of a simple Design Model. Due to the limitations of the Sales phase this model is built with help of regression lines, empirical formulas and rules of thumb. The set of solutions are explored with eight design drivers which originated from the stakeholders and Sales process: Aesthetics, Usage, Performance, Rules, Costs, Space, Comfort and Safety. The design drivers are categorised into three parts: input, constraint and output. The input will follow from the client, where the constraints will follow from the other two stakeholders. The final choice for the output is made by the client, which can be underpinned with help of the output design drivers. This research concludes that design exploration could be an improvement on the current used point-base design method. Since design exploration fully utilises the design freedom available in the early stage design. The solutions produced by the Design Model show reasonable results, which lie within a 10% margin of the existing designs. Due to the limitations of the Sales phase the choice was made to use regression lines. As a result, the design space consists of solutions of which the trend is clearly visible. Nevertheless, the variety within the design space is sufficient enough to create a diversity in solutions. The results produced by the Design Model will be a good starting point in the starting phase. In order to use the results as more than a starting point, the detail level of the calculation methods should be improved. Generating a set of solutions will enable the designer and client to make well-informed decisions. Especially when the client is involved in this process.

Greenhouse gas emissions’ reduction goals of a 50% reduction by 2050 were established by the IMO. As a first step to achieve this reduction already by 2030 this project uncovers how much of the CO₂ emissions it is possible to reduce by combining the available state of the art technology. The reduction of CO₂ emissions is done in two steps. The first step consists in reducing the power demand in terms of auxiliary and propulsion systems. After that, cleaner power supply alternatives are considered to further reduce the emissions. In terms of auxiliary power, heavy consumers such the air conditioning, the lighting or water systems are considered. The reduction of auxiliary power is not only achieved with the introduction of more efficient equipment but also by the introduction of passive design strategies that enhance savings by reducing the loading on the systems. Altogether it is possible to reduce the auxiliary power demand by 33% in comparison with the benchmark design. The reduction of auxiliary power demand has a significant impact on the yearly consumption due to the significant percentage of operational time spent at anchorage. In terms of propulsion power demand, the reductions achieved are even more significant, 51% and 70% power demand reductions are possible at cruising and maximum speed, respectively. The introduction of the Van Oossanen’s Fast Displacement Hull Form (FDHF), the reduction of displacement by making an aluminium hull and the application of the patented Hull Vane® are the main reasons for such a significant propulsion power demand. Finally, the switch in power plant arrangement of the yacht results in further 10% reduction. In this case, simply the change from diesel direct arrangement to a hybrid arrangement leads to yearly savings, mainly because emissions at cruising are reduced due to the power take-off operational mode of the power plant, saving generator set emissions. All in all, it is possible to already achieve a reduction of approximately 41% of the yearly CO₂ emissions on a 50 m motor yacht. One of the most important conclusions to be taken is that all these reductions are possible when finding the optimal interaction between components, from auxiliaries to power plant arrangement. Mainly, the CO₂ emissions reduction followed from a fuel consumption reduction, not yet introducing power supply from renewable energies nor alternative fuels which despite being the way to the future are not yet fully mature and suitable for this specific case.

▼ Wind turbine technology has become one of the most attractive solutions to generate electricity as well as to cope with the global carbon emissions. Having a prospective future in terms of growing worldwide demands, it becomes more important to reduce the Levelized Cost of Energy (LCoE) of the wind turbine which is generally done by manufacturing the structure, such as the rotor blades and tower, larger. Consequently, this so-called upscaling strategy introduces a drawback in terms of more severe fatigue loadings at both the rotating and fixed components, for example due to wind shear effect, turbulence, and tower shadow, if not dealt with properly. Fortunately, a solution from the control engineering field, namely Individual Pitch Control (IPC), emerged in response to this challenge. The idea is to rotate the pitch angle of the blades individually depending on the measured loads, normally from the corresponding blade roots. Conventional IPC incorporates the Multi-Blade Coordinate (MBC) transformation which transforms the individual blade load signals from the rotating into the non-rotating reference frame; resulting in the decoupled signals of tilt and yaw axes. This enables the design of Single-Input Single-Output (SISO) Proportional-Integral (PI) controllers that generate pitch actions at these channels; followed by the reverse coordinate transformation such that the individual pitch actions can be implemented. In reality, however, there are interactions between the tilt and yaw axes, which can be coped with by inclusion of a constant azimuth offset into the reverse MBC transformation. Although the straightforward technique is widely practiced in the literature, no validation on this offset and how it affects the cross-coupling prevail whatsoever. Recently in the literature, an analysis of a wind turbine model with the inclusion of the MBC transformation in the frequency domain revealed the existence of tilt-yaw axes crosscoupling to some extents which invalidates the SISO control system design; confirming that the problem should be treated in the Multiple-Input Multiple-Output (MIMO) control framework. Nevertheless, little attention has been paid to enhance the decoupling by the aforementioned azimuth offset inclusion in which SISO control system design can be made possible. In this study, an extension of the above-mentioned frequency domain analysis was done by including the azimuth offset. Having successfully shown considerable changes in terms of system’s gain, the investigation was continued by using both the linearized and nonlinear NREL 5-MW baseline wind turbine models in which the offset inclusion to the MBC transformation managed to affect the tilt-yaw interactions. The degree of decoupling assessment and the closed-loop stability analysis were done by means of Gershgorin bands. The results showed that the best decoupling effect, stability margins, and robustness could be achieved by inclusion of the azimuth offset of 20◦ for the particular wind turbine model.

▼ In the future, two enormous challenges face humanity: decreasing the carbon emissions and supporting the growing energy demands in the developing regions of the world. These challenges highlight the need for a greater amount of implementation of renewable energy projects. This thesis tackles one such potential project, the modeling of a tidal barrage power plant based in the Gulf of Khambhat off the Western coast of India. The Gulf of Khambhat has a high tidal range of 8-11 m, and has a large amount of energy that is theoretically available. However, only a fraction of this energy is expected to be extractable. A focus was placed on modeling the entire operation of the tidal barrage power plant and understanding the interactions of the local regime with thepower plant.Based on the results, several details about the tidal barrage power plant could be ascertained. 2 possible locations are available for placing the turbines, where sufficient depthsare present. The locations vary in the resultant tidal range available and also in the way the discharge empties/fills the basin. Based on the tidal range alone, the location on the farright of the tidal basin is deemed ideal. The turbine’s resistance to the flow also influenced the energy generation of the power plant. This influence was compared to the case without any resistance, and it was shown that in some scenarios, the resistance provided a positive influence on the energy generation. It was also shown that the barrage itself increases the tidal range available at the site.The 2 biggest influence by the local conditions were the shallowness of the basin and the presence of the tidal flats. These two factors negatively impact the energy generationin the area. The tidal flats in particular act as an obstruction to the flow, preventing a uniform filling and emptying of the basin during operation. The effects of these tidal flats are more pronounced as the water levels during operation drop. Due to this, a greater amount of energy is lost in the 2 way generation mode.The removal of these tidal flats by dredging would create a more uniform depth withing the basin and would lead to a higher energy generation, with upto 34% increase seen in the 2 way generation scenarios.Further, the strengths of the 2D modeling process was seen. For any future tidal resource assessment, not modeling the local conditions could provide highly inaccurate values of the energy generation possible.

▼ AGVs have seen an upward trend in development over the last 60 years. The technology has developed from mechanical bumpers and guided wire navigation to contactless sensors and free navigation technique in the current age. Further, the control on AGVs has moved from central control system to local intelligence which opens up various possibilities with respect to operations as well as applications. The growing trend of AGVs has been due to the sudden growth in digital technology and the ever-increasing demand to reduce human intervention in operations. This has resulted in increased research regarding the implementation of intelligent AGVs in areas of application that have not yet been explored, namely, light metal and forging industry. The major reasons for indulging in autonomous equipment are, increased productivity, reliability and safety since human involvement is either eliminated or largely reduced. However, a major share of the research about intelligent AGVs has been confined to warehouses and port logistics. Therefore, through this research, another area of application is investigated, namely, the light metal and forging industry, and more specifically, the potroom of an aluminium smelter. Hence, the objective of the research is as stated: With the introduction of intelligent AGVs, stochastic behavior needs to be addressed, that is, how would these AGVs react to disturbances created by such random human behaviour and process interference? Therefore, the research focusses on the routing problem in such situations which are dynamic in nature. The research aims to provide a planning approach in terms of dynamic AGV routing under the assistance of a sensor based system that can detect obstacles. The dynamic re-routing of AGVs is addressed using a mathematical formulation as well as a graphical representation. In order to solve the problem at hand, the graphical approach is followed and the objective has been simplified for research purposes. It is simplified as: For instance, if a certain pathway is blocked in the potroom of an aluminium smelter due to such stochastic behavior, how would the AGV find the optimal path? An algorithm is devised in order to answer the above research question and further implemented in Python. Various scenarios of stochastic disturbances is analysed and evaluated accordingly. Therefore, this research develops an algorithm and a subsequent model that is implemented using Python which is used to evaluate the routing of an AGV in the presence of stochastic behavior. It acts as a proof of concept for the problem at hand as it restricts the work to a simplified situation of a single AGV operation. Although this research uses the case of a light metal and forging industry, the same can be applied to industries with similar challenges such as, cement industry, power generation industry, aerospace, construction and so on. Cement, construction and power generation industry deal with environments similar to the light metal and forging industry. Further, in all these application areas, the use… Advisors/Committee Members: Schulte, Frederik (mentor), Meijer, Maarten (mentor), Polinder, Henk (graduation committee), Delft University of Technology (degree granting institution).

In the European Union Road freight transport volume is expected to grow 78% between 2000 and 2030, which results in more trucks on the road network. The worldwide estimated trend shows an increase of 150 million freight vehicles and an increase of 240 million passenger vehicles. The growth of both vehicle classes will have a major impact on the road network and the roads will become congested. Especially in dense urban environments with many intersections. Further, trucks have a detrimental impact on traffic flows, especially at intersections, because of their slow dynamics and large size. In addition, a stopping truck results in higher emissions and fuel consumption compared to a car. However, today’s traffic controllers are not capable of optimizing traffic flow at intersections based on classification of different vehicles. Therefore, it would be beneficial to all vehicles involved if the number of stops for trucks would be reduced to a minimum, by servicing each vehicle class in a different way. Throughout this research the focus is to develop a signalized intersection controller which is able to reduce the number of stops for trucks, while maintaining an equal level of service for the other modes of transport. Extensive literature studies provided important insights into the development of signalized intersection controllers. A selection of the techniques found in the literature is used to develop a new truck signal priority controller design. The basic idea is to use a weighted traffic light schedule in combination with priority weights to enable truck signal priority. The design is evaluated in a case study and simulated for multiple configurations. This leads to an overview of the performance in terms of the number of stops and vehicle delay. From the results several conclusions can be drawn on the optimal weight configuration, which is compared to a state-of-the-art model predictive intersection controller. The results showed an reduction of the total number of stops by 751 and total vehicle delay by 304 minutes for trucks over a week (26,6% and 20,4% respectively). While, the total number of stops and total vehicle delay for cars increased, by 155 stops and 201 minutes (0,1% and 0,3% respectively). However, the overall total number of stops and total vehicle delay were reduced by 596 stops and 103 minutes (0,42% and 0,16% respectively). It can be concluded that the proposed truck signal priority controller design can reduce the number of stops for trucks at a signalized intersection, while maintaining the overall traffic flow at least as good as a state-of-the-art model predictive intersection controller.

▼ <p class="p1">In recent years, a rapid development of the offshore wind power market has taken place. The growing demand for more offshore wind farms and the desire to make this technology more cost-effective has created many challenges for offshore contractors and their technology, particularly for turbine installation vessels. Currently, the most widely used equipment is the jack-up type crane vessels. These vessels have been optimised for turbine installation operations but are now starting to reach their limits in performance, based on the further improvement of the wind turbines, the fact that the wind farms located further and deeper at the sea. As a result, new designs may be better suited to the challenging requirements of the wind farm developers. In practical terms, it is difficult to predict whether a new concept will perform better another. Operational data from past turbine installation vessel operations can be used to identify important parameters that influence performance but is not practical when applied to unconventional designs such as the concept ship, “Wind Turbine Shuttle” designed by Huisman Equipment in the Netherlands. An extensive study is necessary requiring perhaps the development of new analysis tools. This study attempts to identify the major parameters that influence the operations of turbine installation vessels. It investigates with the use of different operational scenarios, how the procedure of installation and transportation of these vessels are influenced by their parameters such as the pre-assembly method of the wind turbine or the wind turbine sizes and their operating environment, using a market and technology review of the wind farm market, a sensitivity analysis of various design parameters and different case strategies investigating the performance of different turbine installation vessels operating in a predefined wind farm location. Because several strategies have shown that weather delays have a major effect on the workability of the vessel, the simulation model uses wave height time series data from measurements made in the North Sea. For the sensitivity studies of design parameters, results show that for any scenario, an optimal value for both significant wave height tolerance and transit speed can be found. The optimal parameters for the scenario designed in this study are similar to the specifications of the Wind Turbine Shuttle. Overall, results show a definite advantage of using a turbine installation vessel such as the Wind Turbine Shuttle over traditional jack-up vessels. However, as the model is based on many assumptions, the accuracy of the results would be significantly improved with additional real life data. Regardless of this, the study has demonstrated the advantage of opting for a systems approach containing various models that are connected to each other. This methodology has many possible future applications, not only for the evaluation of wind turbine installation vessels but for any vessel type employed in the offshore construction… Advisors/Committee Members: Beelaerts van Blokland, Wouter (mentor), Polinder, Henk (graduation committee), Frouws, Koos (graduation committee), Delft University of Technology (degree granting institution).

Due to the intermittency of wind energy this poses new problems and challenges for the future electricity system in the Netherlands. The objective of this report is to identify the challenges for the electricity supply of offshore wind farms and to research how energy storage and alternative wind turbine design can aid in these challenges. The problems experienced and possible solutions are first identified by conducting a literature review and data analysis. Subsequently a Matlab model is constructed to simulate an offshore wind farm and energy storage system. This model is used to determine the most cost-efficient storage technique and the impact of this technique on the future electricity system. Of the challenges for future offshore wind farms do the short-term profile effects have the most influence. These effects negatively affect: 1. the security of supply in the electricity system, 2. the stability of the load on the high voltage grid and 3. the market value of the produced electricity. The impact of these effects is intensified by the strong correlation in power production between the connected (future) onshore and offshore wind farms. To reduce profile effects energy storage is used, the optimal configuration of the storage system has a power capacity between 0.23 and 0.27 times the rated power of the wind farm. For the optimal energy capacity, however, no optimum is found, and the design depends on the desired impact of the system. An analysis on the impact of an optimal design has shown that an offshore wind and energy storage system does not result in an economical feasible system. Short-term profile effect reduction with energy storage, however, is shown to be essential in a future electricity system that is dominated by wind and solar power. The short-term profile effects of wind energy production are correlated too much and will have a too high impact on the system if no energy storage is included in offshore wind electricity production.

▼ With the shift towards a more sustainable energy society, the increase in the electricity produced by renewable energy sources is steadily rising. However the cost of renewable energy sources still remains high compared to the traditional fossil fuel based energy sources. With the total worldwide energy demand also rising, combining renewable energy sources helps to reduce the cost through a shared infrastructure and increase in energy production. This thesis investigates the feasibility of a combination of floating offshore wind and marine current energy. As a basis the Hywind spar type floating offshore wind turbine is used. This 5 MW system is combined with a 1 MW marine current turbine. The characteristics of the current turbine will be examined with the program Aerodyn and the blades are designed with the program Harp_opt. As a cost reduction, the effect of scaling down the weight of the mooring system in combination with reversing the direction of the thrust of the current turbine is also investigated. The program ANSYS AQWA is used to investigate the dynamic behavior of the combined system. The thrust forces of the wind and current turbines are calculated via an external python server and added to the simulation in AQWA. The structure is modeled in a rigid body approximation, assuming no structural deformations. The behavior of the combined system is investigated in 3 operational and 1 survival load case. The operational load cases represent the environmental conditions of the cut-in, rated and cut-out wind speed of the wind turbine. In the fourth load case the system is subjected to survival conditions and the direction of the thrust of the current turbine is reversed. The environmental conditions are simulated with a steady wind velocity and the sea state is modeled using the JONSWAP wave spectrum. In all 4 load cases the system is subjected to a strong current. By using a levelized cost of energy prediction model, a first estimation of the levelized cost of energy of the combined system is obtained. Adding a current turbine to the Hywind spar increases the cost of the initial investments and operational cost of the system, but also increases the total energy generation. Compared to the original Hywind spar, adding a current turbine to the system lowers the levelized cost of energy from 149.4 €/MWh to 142.3 €/MWh. Scaling down the weight of the mooring system lowers the levelized cost of energy to 141.9 €/MWh. From the results of the simulations it is found that using the current turbine during survival conditions has a positive effect on the motions and maximum tension in the lines. It is concluded that by using the thrust of the turbine the weight of the mooring system could be scaled down, but the effect on the levelized cost of energy is minimal and doesn’t justify the increased risk of failure.

▼ Due to the global climate change there is a increasing demand for transportation on renewable fuels. An increasing trend in electric propulsion can already be seen in the automotive industry and this is now also gaining popularity in the maritime sector. Due to limited capacity if the onboard battery, especially electric ferries are becoming more popular, because of the relative short sailing distances. The ﬁrst electric ferry became operational in 2015 in Norway and since than a hand full of electric vessels was developed. An electric vessel requires a charging mechanism to charge while unloading and loading passengers in the port. Besides, generally also a mooring mechanism is necessary. This enables the vessel to turn off the propeller while charging which limits the energy demand while charging. Various systems have been developed already. However, these are not standardized solutions but all one of a kind systems designed for a speciﬁc vessel or ﬂeet. Which of these is the best solution is not easy to determine and strongly depends on the vessel characteristics and the operating environment. To supply the expected increasing demand for electric vessels, a guideline is developed which will help the engineer to ﬁnd a suitable charging and mooring mechanism and to decrease the selection time for this system. The will provide Damen a strategic advantage towards other shipyards in vessel tenders since both the development costs and delivery time is lower. This guideline is developed based on the knowledge gained during a case study for a 81m Ropax ferry, sailing in the surroundings of Vancouver Island. For the case study an engineering design method was selected from literature and applied to this case, for which Damen had a hard time ﬁnding a charging and mooring mechanism. First thought was to combine both into one mechanism, but this is difﬁcult due to conﬂicting functionalities of both systems. Due to the limited time available for the research, the design of the mooring mechanism is not taken into account for the case study. Setting the requirements for the charging mechanism is complex due to the range of different ﬁelds of interest that should be taken into account. However, the requirements of these various aspects are often related in some way to one another. This makes it easy to lose sight of the structure of all requirements. Comparing the functions that the charging mechanism should fulﬁll within these requirements and the existing charging mechanisms, it can be concluded that no suitable system is available yet. The gap between these is deﬁned as a set of three functions; to compensate the tidal difference, deal with misalignments between the vessel and the shore and to provide ﬂexibility for vessel motions. A new design was made which covers this gap. Additional research was done to ensure sufﬁcient ﬂexibility from the power cable, since this proved to be critical in the state of the art systems. From the knowledge gained during this case study, the guideline is developed.

As wind turbines continue to increase in size, so do the loads acting on the drivetrain. To handle the higher loads the mass of the drivetrain needs to increase. A better understanding of this mass increase can result in lighter drivetrain design and provide an insight which drivetrain design has the lowest mass potential for large rotor diameters. In this thesis the limiting mechanisms, mass and torque density of three wind turbine drivetrains are investigated for an increasing rotor diameter. The limiting mechanisms in this thesis provide a theoretical limit to the minimum required mass of a drivetrain for increased loading. Through an extensive literature study the limiting mechanisms are found and three scaling models are developed to calculate the torque density of the drivetrains. The drivetrains that are being considered in this thesis are the drivetrain with gearbox and high-speed generator, the direct drivetrain and the hydraulic drivetrain. The following research questions are answered in this thesis: • What are the limiting mechanisms of the three investigated drivetrain types? • What are the achievable torque densities of the three investigated drivetrain configurations for increasing rotor diameters? Two limiting mechanisms are found for the drivetrain with gearbox and high-speed generator: Tooth flank stress (1.72 GPa) and Root bending stress (0.24 GPa). The Tooth flank stress is found to be governed by the Hertzian contact strength while the root bending stress is governed by the flexural strength. Two limiting mechanisms for the RFPMSG are found for the airgap flux density (1 T) and the current loading (30 - 200 kA/m) in the generator windings. The airgap flux density is limited by the saturation of the stator teeth material in the generator whereas the current loading is limited by the heat dissipation of the windings and stator laminations. For the hydraulic pump, the limiting mechanism is found at the interaction of the camring and the cam roller. The maximum stress that is allowed at this point is determined by the Hertzian contact strength of the material and is found to be (1.72 GPa). Using the limiting mechanisms of the three drivetrain configurations, scaling models for the mass and torque density of the three drivetrains have been developed.

▼ Over the years, the use of PM machines has been increasing in the offshore wind industry and marine industry. The industries thrive on efficient function of the PM machines. These machines are prone to electro-mechanical faults due to environmental conditions and maintenance. Out of all these faults, stator internal faults are concerning as they can lead to insulation failures which may take around 30 seconds to expand and lead to a fire on ships, or on wind turbines. These type of faults develop gradually, which gives the opportunity to control the fault currents before they reach dangerous levels. Rolls Royce Marine AS is also working to tackle this problem for their hybrid propulsion shaft generator. DNVGL requires the generator to be made electrically dead during such event and the long-term propulsion should not be affected. During such conditions, WTs are either turned off or field weakening is used to develop a fault tolerant control (FTC) by the help of power electronics for the WT. FTC helps the machine not to be turned off completely, but less power is generated during fault conditions. An alternative efficient field weakening method using a Dual Rotor PMSM was suggested for both the applications. The DR-PMSM has two rotors instead of one, with identical surface mounted magnets on both rotors. One of these rotors has the capacity to rotate with respect to the other, in order to reduce the flux or completely short the flux path by misalignment of rotors. The machine stator is exactly like the conventional PMSM. The machine is capable of reducing the induced emf to zero by field weakening. In this thesis a transient 3D finite element model is presented to test the credibility of the machine. A 2D FEM of a conventional PMSM was also built to check the validity of the machine. It is seen that torque is a function of the active length of the machine, and if a gap is introduced between the rotors then the total length of the machine must be increased. Also, axial flux component which induces eddy currents in the stator teeth was studied. By modeling anisotropy in the stator iron, certain hot spots could be seen in the middle part of the stator. The forces that were in the shifting mechanism were studied and it was concluded that machine cogging can be reduced to reduce the effect of these forces. A machine prototype was also built which confirms the field weakening capability of the machine. The DR-PMSM works like a conventional PMSM but with flux weakening capabilities and can be implemented on marine and wind turbine applications for these type of fault conditions.
